A high strength concrete with 28 day strength up to 80 MPa from superfine sand with fineness modulus of 0.56 is obtained.It has a permeability resistance of 4.0 MPa and small shrinkage creep.Experiment and study were carried out on its pore structure
hydration products and microhardness of transient area in cement paste and aggregate interface. The essence for high strength of such concrete was revealed.
